The objective of this study was to estimate the prevalence of low serum and red blood cell (RBC) folate values of Mexican American (MA), Cuban (C), and Puerto Rican (PR) women examined in the Hispanic Health and Nutrition Examination Survey, 1982-1984. Serum and RBC folate were determined for all women aged 18-44 y by use of a radio-assay kit. The percent of women with low serum folate (less than 6.8 nmol/L) was 11.9% for MA, 10.1% for C, and 8.1% for PR. The prevalence of low concentrations of RBC folate (less than 363 nmol/L) was 7.8%, 16.7%, and 13.6% for MA, C, and PR, respectively. The percentages of women with reduced tissue stores of folate were 4.3% for MA, 6.0% for C, and 4.0% for PR. Years of education completed and poverty status did not significantly affect folate concentrations; however, the prevalence of low folate concentrations among users of vitamin or mineral supplements was significantly lower than it was among nonusers in selected subgroups.
